Purpose: To explore the efficacy and safety of a self-improved continuous bladder irrigation (CBI) sensor device after transurethral resection of the prostate (TURP)., Materials and Methods: A total of 160 patients with benign prostatic hyperplasia who received TURP from June 2021 to May 2022 were selected. According to the envelope randomization method, patients were divided into a control group (80 cases) and study group (80 cases). In the control group, the speed of bladder flushing fluid was adjusted according to the clinical experience of nurses. On the basis of the control group, the self-improved CBI sensor device was used in the study group to observe the postoperative comfort and complication rate in the two groups., Results: The comfort of patients in the study group was significantly higher than that of patients in the control group (97.50% vs. 88.75%, P = .023), and the number of postoperative complications in the control group was significantly higher than that in the study group (8.75% vs. 1.25%, P = .021). Meanwhile, the average amount of irrigation fluid in the study group was obviously lower than that in the control group (26.4 L vs. 27.8 L, P = .011). In addition, patients in the study group had a significantly shorter hospital stay than the controls (3.3 days vs. 3.6 days, P = .005)., Conclusion: Implementation of the new self-improved CBI sensor device for patients after TURP can improve their awareness regarding disease-related knowledge, alleviate their fear and anxiety, improve their compliance and comfort with treatment and nursing, and reduce the incidence of complications.

Purpose: Tamsulosin, a medical expulsive therapy (MET), was always recommended for patients with distal ure-teral calculi less than 10 mm. The aim of the systematic review was to assess the efficacy and safety of tamsulosin in MET compared with placebo., Materials and Methods: A comprehensive search was conducted in the databases PubMed, EMBASE and Web of Science for relevant articles, covering all the literatures published until April 2018. All placebo controlled trails were identified in which patients were randomized to receive either tamsulosin or placebo for distal ureteral calculi., Results: A total of seven placebo controlled studies including 4135 patients met the inclusion criteria and were involved in the review. We found that tamsulosin was associated with a significantly higher expulsion rate (ESR) [odds ratio (OR) = 1.10, 95% confidence interval (CI) = 1.00-1.21] than placebo in patients with distal ureteral stones less than 7 mm. The ESR ranged from 67.0%-90.7%. But the significant difference was better seen in pa-tients with distal ureteral stones less than 10 mm (OR = 1.11, 95% CI = 1.01-1.21). Even though tamsulosin has a higher incidence of retrograde ejaculation than placebo, no significant difference was observed in the incidence of other adverse events., Conclusion: The results of the current meta-analysis indicated that tamsulosin was superior to placebo in its effi-cacy for distal ureteral stones though retrograde ejaculation was worse with tamsulosin use. It should be a safe and effective medical expulsive therapy choice for distal ureteral stones when stone sizes are less than 10 mm.
